High-efficiency HVd.c. generating stations

HVd.c. generating stations are advantageous for power transmission over lon g distances. In the case of remote generation, the possibility of operating these systems with generation and rectification equipment intimately conne cted, with the a.c. filters removed, has been discussed frequently in the p ast, with its many advantages presented, but as yet without such a system b eing realized. Among other concerns, it would seem that the removal of the a.c. filters is not feasible. In this paper a new configuration is proposed , whereby harmonics are eliminated within the converter, and thus the a.c. filters may be removed without further implications.
